Tom Street – bollotom@fsmail.net – has kindly offered to make Piccadilly Line signalling diagrams available to developers. I have seen these diagrams by David Hough and Matt Davis and they are extermely clear and detailed. Please email Tom if you would like a copy (they are in Microsoft Powerpoint format). Tom is also enquiring about allowing us to upload them to the website for general access.
Tom has also drawn attention to the “Tubeprune Network”, which is an unofficial web site for professional railway people working for London Underground and for those interested in the London Underground railway system. This site contains signalling diagrams for the Northern Line, Victoria Line and others, together with a great deal of other underground related information. Links are as follows:-
